The 8.8 swap is very common, and has lots of advantages, such as disc brakes and readily available Suregrip centers. It would cost about $200 to have the rear end cut, but you need to buy another short side axle as well, so that will add to the price. The perches also have to be welded in the correct locations, and you would have to buy the correct perches. There is undoubtably more than one thread here that explains the entire process, and I was hoping Moparmatt2000 would chime in here, he’s doing his right now!
